With an ever-increasing number of vehicles and pedestrians using our transport networks, drivers encounter more and more distractions. Road traffic accidents happen for a number of reasons, many of which are linked to human error. A large number of incidents could be avoided if drivers were more aware of the speed they were travelling. Informing and advising drivers of excessive speeding are key benefits of Vehicle Activated Signage.

Coeval’s Vehicle Activated Signs (VAS) are designed to support speed awareness – warning drivers exceeding safe speed limits and encouraging them to slow down. We design, build, install and maintain bespoke technology solutions that advise, inform, and protect road users and help to reduce driver error.

Our products have a robust build, with high-power LEDs that can be seen clearly even in hazardous conditions or inclement weather. With bespoke VAS we can provide the right road signage for all rural and urban environments.

    What our clients say

    Connect Plus Services M25 Dartford Crossing

    ‘Even a short closure of the tunnel causes great congestion in the area, and if an over height vehicle were to cause that level of damage, the tunnel could be closed for hours, if not days, which would bring the whole of the South East of England to a standstill.

    When the Coeval over height vehicle detectors were first installed, we were talking about 10’s of vehicles a day that we were stopping; we are now down to low single figures, 4 or 5 vehicles a day we need to extract for being over height, so it’s a great improvement in efficiency through the crossing.’

    Platinum Electrical Ltd

    ‘Having used Coeval for the first time, we found them to be friendly and really helpful in ensuring we received the correct item we required. We were happy with the extremely quick response times and professional service they offer. We would definitely recommend their services to others.’
